Namespace:  System.ServiceModel.Syndication
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class Rss20FeedFormatter : SyndicationFeedFormatter, 

The Rss20FeedFormatter type exposes the following members.

Public methodRss20FeedFormatter()Creates a new instance of the Rss20FeedFormatter class.
Public methodRss20FeedFormatter(SyndicationFeed)Creates a new instance of the Rss20FeedFormatter class with the specified SyndicationFeed instance.
Public methodRss20FeedFormatter(Type)Creates a new instance of the Rss20FeedFormatter class.
Public methodRss20FeedFormatter(SyndicationFeed, Boolean)Creates a new instance of the Rss20FeedFormatter class with the specified SyndicationFeed instance.

Public propertyFeedGets the SyndicationFeed associated with the formatter. (Inherited from SyndicationFeedFormatter.)
Protected propertyFeedTypeThe instance derived from SyndicationFeed that is associated with the Rss20FeedFormatter instance.
Public propertyPreserveAttributeExtensionsGets and sets a value that specifies whether to preserve attribute extensions during serialization.
Public propertyPreserveElementExtensionsGets and sets a value that specifies whether to preserve element extensions during serialization.
Public propertySerializeExtensionsAsAtomGets and sets a value that specifies whether to serialize extensions within the Atom 1.0 namespace.
Public propertyVersionGets the syndication version used by the formatter. (Overrides SyndicationFeedFormatter.Version.)

Public methodCanReadVerifies whether the specified XmlReader contains a valid RSS 2.0 syndication feed. (Overrides SyndicationFeedFormatter.CanRead(XmlReader).)
Protected methodCreateFeedInstanceCreates a new SyndicationFeed. (Overrides SyndicationFeedFormatter.CreateFeedInstance().)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadFromReads an RSS 2.0 syndication feed from the specified XmlReader instance. (Overrides SyndicationFeedFormatter.ReadFrom(XmlReader).)
Protected methodReadItemReads a syndication item from XmlReader instance using the SyndicationFeed instance.
Protected methodReadItemsReads in a collection of SyndicationItem instances from the specified XmlReader.
Protected methodSetFeedSets the SyndicationFeed instance associated with the Rss20FeedFormatter. (Overrides SyndicationFeedFormatter.SetFeed(SyndicationFeed).)
Public methodToStringGets a string representation of the SyndicationFeedFormatter instance. (Inherited from SyndicationFeedFormatter.)
Protected methodWriteItemWrites the specified SyndicationItem instance to the specified XmlWriter.
Protected methodWriteItemsWrites a collection of SyndicationItem instances to the specified XmlWriter.
Public methodWriteToWrites the SyndicationFeed associated with the Rss20FeedFormatter to the specified XmlWriter. (Overrides SyndicationFeedFormatter.WriteTo(XmlWriter).)

Use this class to serialize instances of SyndicationFeed and to create instances of SyndicationFeed from XML documents that represent RSS 2.0 feeds. If you have derived a class from SyndicationFeed and want to serialize it, use the Rss20FeedFormatter<TSyndicationFeed> formatter.

The following code shows how to create a SyndicationFeed and serialize it to RSS 2.0.

            SyndicationFeed feed = new SyndicationFeed("Test Feed", "This is a test feed", new Uri("http://Contoso/testfeed"), "TestFeedID", DateTime.Now);
            SyndicationItem item = new SyndicationItem("Test Item", "This is the content for Test Item", new Uri("http://Contoso/ItemOne"), "TestItemID", DateTime.Now);

	    List<SyndicationItem> items = new List<SyndicationItem>();
            feed.Items = items;

            XmlWriter rssWriter = XmlWriter.Create("RSS.xml");
            Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter(feed);
